Add lint writing documentation [Rendered](https://github.com/phansch/rust-clippy/blob/adding_lints/doc/adding_lints.md) This adds a new documentation page that explains how to write Clippy lints. It guides the reader through creating a `foo` function lint. I plan to iterate a bit more on the prose of some sections, but I think the general structure is fine now, so I'm looking forward to feedback =) One thing I'm not sure about: I felt like this is too big for CONTRIBUTING.md so I put it into a new `doc/` directory. I can imagine having more documentation in the future, so we might even want to create a book using mdbook instead? Or should everything go into CONTRIBUTING.md? Further things left to do: - [x] Link from CONTRIBUTING.md - [x] Remove things covered in this guide from CONTRIBUTING.md - [x] Section about `clippy::author` attribute - [x] Run `remark-lint` on CI over the `doc` directory and fix things
